Peakedness refers to the sharpness or flatness of a probability distribution, specifically describing how concentrated the data is around the mean. It is often assessed in conjunction with other moments, such as skewness, to provide a more comprehensive understanding of the distribution's shape. A distribution can be classified as leptokurtic (high peakedness), platykurtic (low peakedness), or mesokurtic (normal peakedness), which helps in evaluating the likelihood of extreme values or outliers.
